DC police officer guilty of killing mistress, baby

UPPER MARLBORO, Md.
- A Maryland jury has convicted a District of Columbia police officer of killing his mistress and leaving their baby daughter to die in hot car.

The Prince George's County jury returned the verdict Thursday evening against Richmond Phillips on two counts of first-degree murder.

Phillips was arrested in June 2011 after police found the body of 20-year-old Wynetta Wright in the Oxon Run Stream Valley Park. Her 1-year-old daughter, Jaylin, was found dead nearby in a car seat in Wright's car. Police say the girl may have died as a result of exposure to the heat. Court records show Phillips and Wright were involved in a paternity dispute.

Prosecutors say Phillips faces life without the possibility of parole plus 20 years at sentencing March 22.
